Diagnostic accuracy of PET/CT in patients with extranodal marginal zone MALT lymphoma.

Background: (18)Fluoro-2-deoxyglucose ((18)FDG) positron emission tomography (PET) is widely used for initial staging and follow-up in patients with malignant lymphoma. While earlier studies suggested a limited role for PET in extranodal marginal zone mucosa-associated lymphoid tissue (MALT) lymphoma patients due to their non-FDG avidity, more recent reports have suggested that the issue is controversial. In the present study, we evaluated the diagnostic accuracy of PET integrated with CT (PETCT) in patients with MALT lymphoma and assessed its reliability in clinical staging and monitoring response.

Laparoscopic adjustable gastric banding surgery for morbid obesity: imaging of normal anatomic features and postoperative gastrointestinal complications.

Objective: The purpose of this essay is to describe the normal anatomic findings after laparoscopic adjustable gastric banding surgery and the imaging findings of postoperative gastrointestinal complications.

Conclusion: With the increasing prevalence of morbid obesity, laparoscopic adjustable gastric banding surgery has evolved to be a leading surgical technique. Radiologists need to be familiar with the normal anatomic findings after laparoscopic adjustable gastric banding surgery and with the imaging findings of postoperative complications.
